Well, it seems I will wait for 3D printed one from 50koruny. If something breaks, I will print new part ;)

I wonder about quality of those decals. Ferdinand's decals are very thick. Probably the best option is to make stencils.

Would love to see some close ups of the suspension as well confirmation on materials used. Thanks! 8)

I can't take better pictures than Hooben, at my tank all parts looks similar.
It look like a Christies suspension, but it isn“t.
Above the suspensionarm is a spring centered by a screw.
This screw also limits the spring travel.
when the tank is normally on flat ground, the screws are at the stop, in my opinion this is due to springs that are too tight.
The suspension can only compress.

So that's what a Chinese Christie suspension looks like? :haha: :haha: :haha: :haha:

To get even deeper into the weeds, Hooben has copied a page from Carlos Ghosn's book where one cannot tell the difference between parts used between a Nissan & Renault. That is the same exact arm I have on the Hetzer, a latter nylon version they made to replace the original PLA arm that breaks if you look at it too harshly.

Funny, but I never knew that Nuffield & Skoda shared such design information during the height of the war. :wtf:

I guess the good thing is the suspension arm is mostly hidden due to the design of the Cromwell suspension.

Just got an inside look at Warprint's Cromwell suspension & know the wait will certainly be worth it. Expect an update soon since Tomas is assembling the prototype this week.
